Magnetic activity dependence of the electric drift below L=3

More than two years of magnetic and electric field measurements by the Van Allen Probes are analyzed with the objective of determining the average effects of magnetic activity on the electric drift below L=3. The study finds that an increase in magnetospheric convection leads to a decrease in the magnitude of the azimuthal component of the electric drift, especially in the night-side. The amplitude of the slowdown is a function of L, local time MLT, and Kp, in a pattern consistent with the storm-time dynamics of the ionosphe ...

Typical values of the electric drift E \texttimes B / B 2 in the inner radiation belt and slot region as determined from Van Allen Probe measurements

The electric drift E \texttimes B/B2 plays a fundamental role for the description of plasma flow and particle acceleration. Yet it is not well-known in the inner belt and slot region because of a lack of reliable in situ measurements. In this article, we present an analysis of the electric drifts measured below L ~ 3 by both Van Allen Probes A and B from September 2012 to December 2014. The objective is to determine the typical components of the equatorial electric drift in both radial and azimuthal directions. The dependenc ...
